IS Beheads Briton David Haines, Threatens to Execute Another Briton, Alan Henning

The Islamic State (IS) released a video of beheading its British captive David Cawthorne Haines and threatening to execute another Briton, Alan Henning.

The 2 minute, 27 second video, entitled, "A Message to the Allies of America," was produced by the IS' al-Furqan Media Foundation, and was posted on Twitter on September 13, 2014. Similar to the previous videos of beheading American journalists James Wright Foley and Steven Joel Sotloff, the latest shows the victims decrying his government's actions against the Islamic State and holding its leadership responsible for his death. Haines said to UK Prime Minister David Cameron: "You entered voluntarily into a coalition with the United States against the Islamic State, just as your predecessor Tony Blair did, following a trend amongst our British prime ministers who can't find the courage to say no to the Americans".

The executioner, who sounds to be the same man who appeared in the videos with Foley and Sotloff, told Cameron and the British government that their alliance with the U.S. will only "accelerate your destruction" and will drag the British people into "another bloody and unwinnable war".
